BLOCK MOLD.

Application filed December 9, 1922. Serial No. 605,902.

To all whom t may concern:

Be it known that l, GUs'rAv EY, a citizen of the United States, and a resident of the city of New York, borough of Manhattan, in the county and State oi' New' York, have invented new and useful improvements in Block Molds, of which the following vis a full, clear, and exact description.

This invention relates to block molds and was primarily designed for use in making concrete blocks..A

In molds constructed with miter joints a great deal of diiliculty is experienced in f1tting the molds together after they have been used for some time due to the fact that a certain amount of concrete or the like adheres to the molds. If the molds with miter joints are fitted together with concrete adhering to them the members are likely to be thrown out of proper alinement and the result will be blocks that are not accurately shaped. Other types of molds are constructed and the transverse members are attached to the longitudinal members by fitting a plate on one into a slot formed in the other. This construction is also unsatisfactory because the slots are continually blocked by the concrete.

The general object of this invention `is the provision of a simple and etlicient mold so constructed that the members may be quickly assembled and disassembled.

A further object of the invention is the provision of a mold, the members of which are provided with simple means for connecting then together, the connecting means being so constructed that the deposits of concrete or the like do not cause any great amount of trouble or the possibility of disalinement resulting in improperly shaped blocks.

Another object of the invention is the provision of a mold, the members of which are formed with straight sides thus introducing cheapness of manufacture and simplifying the replacement of worn and destroyed parts.

These objects are accomplished by constructing from sheet material longitudinal members having hollow longitudinal beadings with straight sides, transverse members provided with hollow straight-sided headings extending longitudinally of the transverse members, forming notches in the ends of the transverse members for itting over the headings on the longitudinal members,

mounting on the headings of the longitudinal members guides for projecting into the tubular member formed by the headings of the transverse members, and locating in each section formed by the longitudinal and transverse members means for Xing the depth ot the block. l y

These and other objects of the invention will be more clearly understood from the following detailed description and accom panying drawings.

Figure 1 is a top plan View of a portion of the mold assembled;

Figure 2 is a vertical section along the line 2-2, Figure 1, showing a cross section of the longitudinal member and a side elevation of a transverse member;

Figure 3 is a section along the line 3 3, Figure 1, showing sections of the transverse members;

` Figure 4 is a perspective View of a section from which the longitudinal members are constructed;

Figure 5 is a perspective view of an end transverse member;

Figure 6 is a perspective view of one of the sections from which the transverse members are constructed;

Figure 7 is a perspective view of a block that may be formed in the mold.

Referring to the above-mentioned drawings, the invention includes end longitudinal members 10, central longitudinal members 11, end transverse members 12 and central transverse members 13. Each end longitudinal member 10 consists of a plate 14 in which a beading or rib 15 is stamped, the heading having straight sides as shown in the figures. A. plate 16 is mounted on the back of the plate 14; and is welded thereto, forming a side longitudinal member, as shown in Figures 1 and 3. rlhe central longitudinal members 11 are formed by abutting two of the plates 14 with the headings 15 extendingoutward. These plates 14C are then attached together vby any means such as welding, thus forming a unit.

The end transverse members consist of a plate 17 in which a beading or rih 1.8 is formed. This heading or rib 18 is hollow and has straight sides, as shown in 'Figure 6. Notches 2O are cut in the plate and so shaped that they will lit over the heading 15 ot the longitudinal members 1() and 11. A plate 19 having notches 21 cut in its ends is mounted on the back ot the plate 17 and is welded thereto thus forming a unit which serves as an end transverse member. 1n forming a central transverse member 13, two plates 17 are placed back to bach and welded together thus forming a unit with a channel extending the length of it and being equal in width to twice the depth of the beading.

The headings 15 of the longitudinal members and 18 of the transverse members each have vertical front walls 22 and inclined side walls 23 which slope toward the iront wall from the base. Mounted on the front wall 22 of the beading 15 ot the longitudinal members 10 and 11 are guides 24. These guides are .welded to the front wall. The guides 24 are formed from a plate which is bent to form a base 25, two side Y members 26 extending at right angles to the base 25, and two inclined members 27 which slope inward as shown in Figures 1 and 4. The base 25 is placed parallel to the wall 22 and welded thereto. The length of each guide 24 except the one mounted on the longitudinal members is equal to the inside measurement across the channel formed by the headings 18 ot the cent-ral transverse members 13. The guides 24 mounted on the ends of the longitudinal members are smaller inA size than the others so that they will fit into the channel formed by the beading 18 of each of the end transverse members. The guides 24 are spaced apart any desired distance, depending on the size of the block it is desired to mold.

Frames 29 are provided for carrying the plaques 30. These plaques are provided for mounting on the bottom of each section of the mold for supporting the concrete and giving it a straight face. The area of the plaque 30 is equal to the area ot a side of the block it is desired to mold 1n assembling the mold, a side longitudinal member 10 is placed against a wall.A An end transverse member is then placed in position, the channel formed by the plate 19 and the beading 18 being projected over the end of a guide 24 mounted on the beading 15 of the side longitudinal member. A plaque 30 is then mounted in position, projecting under the headings of the end transverse memjber and the longitudinal member; A centra-l transverse member 13 is then placed in position, the guide 24 fitting into the channel formed by the beadings 18. Another plaque is placed in position on the other side of the central transverse member 13. After any desired number of transverse members have been placed in position, a central longitudinal member 11 is placed parallel to the end longitudinal member 10 and the guides 24 projected into the channels in the transverse members. Thus between each pair of transverse members located between the longitudinal members a mold is formed for a complete block. The depth of the block will depend. on the height a plaque is supported from the foundation on which the mold is assembled.

After the mixture from which the blocks are to be -formed is placed in the mold the upper surface is smoothed ofi' by means ot a trowel or any other suitable tool. It concrete adheres to any oi' the members it is easily removed since it only can attach to straight outside walls 1 would state in conclusion that while the illustrated example constitutes a practical embodiment ot my invention 1 do not limit myseliC strictly to the exact details herein illustrated since manifestly the same can be considerably varied without departing from the spirit of the invention as defined in the appended claims.
